PURPOSE:To omit an exclusive input part for a RUN command or the like and to produce a sequencer economically by using a process input part as an input part for a RUN command signal and a STOP command signal and forming a detecting means for said inputs. CONSTITUTION:The sequencer is formed by a control means (CPU)1, an input device 2, an external apparatus 3, etc. and the process input part 4 in the input device 2 is used as the input part for a RUN command signal and a STOP command signal to input these signals, The RUN and STOP commands are detected by a program stored in the CPU1 and the sequence of the external apparatus 3 is controlled by the CPU1. When the STOP command signal is inputted, the operation of the external apparatus 3 is stopped. Consequently, the exclusive input part for inputting the RUN and STOP command signals can be made unnecessary and the sequencer can correspond to various types of input apparatuses. |
